The Sheffield-based group has since taken on more staff to bring its headcount to 650.
Sumo’s finance director David Wilton said: “We are aiming to get to between 700 to 750 at the end of this year.
“Now we’ve got nine studios in three different countries. We are keen to recruit more in those locations.”
These nine locations include two in Yorkshire, Sheffield and Huddersfield.
Mr Wilton said 2018 was a “great” year for the group in terms of projects.
